To all whom it may concern:

Be it known that I, MARION WARREN, a citizen of the United States, andresident of Rochester, in the county of `Monroe and State of New York,have invented new and useful Improvements in the following is aspecification. l

My invention relates to improvements in hose nozzles. I have shown myinvention in the drawing which is described in this specification in itsapplication to a hose nozzle, but it is obvious that itis adapted forother uses where the outflow of fluid is to be regulated and controlled.

In the drawing z-Figure view, partly in section, zle embodying myinvention, with the valve wide open. Fig. 2 is a plan view, partly insection, showing the valve nearly closed.

A is the connecting flange, screw threaded l isv a plan -upon itsinterior, by means of which the nozzle is connected to the end of therubber hose in the usual manner, a a are branch pipes through which thewater or other fluid is carried and delivered at the rear end of thedelivery section B of the nozzle. The delivery section B of the nozzlehas a delivery aperture b at one end,

at the opposite end and within'the delivery section B and axiallydisposed therein is a valve stem D, the head of which Z is properlyproportioned with respect to the delivery aperture b to either closewholly or partially or open the same as the valve stem D islongitudinally moved.

Preferably screwed to the rear end of the delivery section is a guidetube E through which the rear end of the valve stem D passes. Around thevalvestem and within the delivery section B is a helical spring F, oneend of which abuts upon the nozzle and the other abuts upon the valvestem, so that the spring constantly tends to throw the valve stem toclose the valve. The head d of the valve stem D when the valve stem isin its most advanced position closes the delivery aperture b, and therear end of the stem D projects beyond the guide tube E and upon itsprojecting end is screwed a finger piece Gr which preferably fits uponthe guide tube E. The outer surface of the guide tube E carries Nozzles,j of which i showing` a hoser nozlbe variously a valve stem aperture crear end; a valve stem `throw the valve stem l with the finger piecescrew threads c upon which threaded portion isrmounted a nut X which canbe screwed along the guide tube E to any desired position.

The mode of operation is as follows: The operator by means of the fingerpiece G pulls back the valve stem D and permits the escape of the fluidfrom the nozzle. When it is desired toy cut off the escape of the fluid,the

valve stem is allowed to close under the influence of the spring F. Ifit is desired to adjust the nozzle to give a gentle spray for certainpurposes by only partially opening the valve stem, this may be effectedby screwing the nut X along the guide tube E until it comes `in contactwith the linger piece Gr and holds it at any desired position to giveany desired stream. It is obvious that by means of the finger piece Gthe stream may be increased at any time over what it is set for Vbymeans of the nut X. By adjustment of the nut X it is therefore possibleto arrange, despite the operation of the spring F, that the nozzle shallnormally give any desired stream and this stream may increased stillleaving the minimumy adjustment of the nut X.

In Fig. l the nozzle is shown in its most open position, the nut X beingpositioned to give a minimum or fine spray stream when the finger pieceisA released. In Fig. 2 the nozzle is shown minimum adjustment by thenut X.
